This is IMO even a VERY BIG FRAUD SCHEME!
It works as follows:
Broker replaces Client's order with its own order whereby changing the Bid to $0.30 from $0.35 (the original order never gets to the exchange!). If that new order then gets filled in the market, the broker "sells" it to the Client and makes a profit of the difference, ie. $0.05 !
The broker can never lose, it's a guaranteed profit for him, even more: when also the commission paid is considered... Client pays the commission AS WELL this kind of slippage fraud.
Gangsters!
I just wonder why none of these sleeping market watchdogs themselves catches such obvious fraud crimes committed by one of the biggest brokers in the industry...
Black scholes formula allows for this blatant fraud to happen. Trump was going to solve it in his second term but that’s why citadel and the big brokers helped the democrats cheat in the election.
S.b. since it's a listed stock...) with low vol & low avgvol. I think the market of the stock is NasdaqCM. IV of the OTM strike used in the order is about 130%, it's a biotech stock (they often have such high IVs). And: it's a GTC limit order and I haven't changed the Bid since I initially submitted it.
